I have tried a guy's titanium carpenters hammer, Light weight but delivers a blow like a much heavier hammer. I Am supposedly retired, contractor and do most of my work with a nail gun. The titanium hammers are expensive. The explanation of the hammer was that it is also like titanium golf clubs. I remember as a kid on the ranch hammering pieces of wire in the blacksmith shop on the big anvil and the wire would heat up. the compression load on the wire and hammer creats heat. Titanium does not compress as much as steel, more energy is delivered to the nail. I haven't seen any titanium body hammers. I am building a helve hammer and Minny pulmax type machine. too much tennis elbow from construction work in my younger days.
